To avoid water damage or scalding due to valve operation, drain pipe must be connected to valve outlet and run to a safe place of discharge. Drain pipe must be the same size as the valve discharge connection through- out its entire length and must pitch downward from the valve.

ELECTRICAL WIRING
NOTE: If it is necessary to replace any of the original wiring, it must be replaced with 105°C wire or its equivalent, except all black wires must be replaced with 150°C wire or its equivalent.
NOTE: Heaters are factory wired for 240V power supply, except Cal Code units wired for 120V Power Supply.
The Electronic Intermittent Ignition Device automati- cally lights the pilot and main burners upon a call for the heat. The heater is supplied with a dual voltage trans- former for 120V or 240V input power hookup.
For 120 V input power to the unit, connect the black wire to the “L1” or hot leg of the power supply. Connect the white wire to the “L2” or neutral leg of the power supply. Attach the wire nut to the red wire. There should
be no connection to the red wire for 120V operation.
Fig. #9240
For 240 V input power to the unit, connect the black wire to the “L1” or hot leg of the power supply. Connect the red wire to the “L2” or second hot leg of the power supply. Attach the wire nut to the white wire. There should be no connection to the white wire for 240V operation.

| NOTE: Input power to the heater (120/240V) should be |
|
| supplied from the load (Pump) side of time clock or |
|
| switch. Connecting heater to continuous power source |
|
| will allow "Fail" indications (service and pressure switch) |
|
| when pump is not operating. |
